In this sketchup video tutorial, Justin Geis provides
some useful sketchup tips for generating gears with the use of circle, offset
and rotate tools inside sketchup. You don’t have to use any sketchup extension
for this purpose.
Some useful tips :-
While going to produce geometry like this, initially you have
to focus on the number of segments in your circles. SketchUp does not have the
ability to draw “pure” curves. As an alternative, the curves are developed with
a set of individual segments, which are arranged by providing a number with the
circle tool turned on. The number of teeth in your gear can be modified by
fixing the number of segments in your circle.
As for instance, let’s draw 2 circles maintaining the
similar radius, one with 24 sides, and one with 36 sides.
If the offset tool is applied to generate a slightly
larger circle and draw in some teeth, it is possible to employ the rotate tool
to copy the teeth around the radius. Here, the circle having more segments
contain more teeth.
As soon as the circle is drawn, draw a slightly larger circle
by applying offset tool. After that, draw lines to the equivalent segment
points to start a tooth. The scale tool can be applied to curtail this line
(hold the control key for constant scaling). It is the perfect time to choose
your circle, right click and choose make center. This will arrange a control
point at the center of your circle that should be applied to copy your tooth in
rotate mode.
As soon as you’ve detailed out one tool, the rotate tool can
be used in copy mode to produce the rest of your teeth. You may require to get
into and remove some left over geometry.
Now, go in and detail out the remaining gear. While
accomplishing this, it’s vital to recognize the math of how you’re parting your
gear up.
If it is required to draw 6 holes in your gear, just
split the number of degrees in a circle (360) with the number of holes required
by you for creation. After that, it is possible to draw your hole as per your
choice, then generate copies along the number of degrees you worked out.
After completing this, just remove your leftover
geometry and with the use of the push/pull tool extrude your gear into 3d.
